Maintaining a healthy lifestyle often involves keeping track of your calorie intake. Whether you want to lose, maintain, or gain weight, understanding your daily calorie needs is crucial. The National Institute Of Health Calorie Calculator is a useful tool that can help you determine the number of calories you should consume daily based on your individual factors. In this article, we will explain how to use this calculator and provide an example to illustrate its functionality.
Formula
The calculator utilizes the Basal Metabolic Rate (BMR) formula to estimate your daily calorie requirements. For men, the formula is:
BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age)
For women, the formula is:
BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age)
After calculating the BMR, the calculator adjusts the result based on your selected activity level. The available activity levels are sedentary, lightly active, moderately active, very active, and super active.
How to Use
Using the National Institute Of Health Calorie Calculator is straightforward. Follow these steps:
- Input your weight in kilograms.
- Input your height in centimeters.
- Enter your age in years.
- Select your gender (male or female) from the dropdown menu.
- Choose your activity level from the second dropdown menu.
- Click the “Calculate” button.
The calculator will display your estimated daily calorie intake in the “Calories per day” field.
Example
Suppose you are a 30-year-old female, weighing 65 kg, with a height of 165 cm, and you lead a moderately active lifestyle. After entering these values into the calculator and clicking “Calculate,” you will find that your estimated daily calorie intake is 1,951.19 calories per day.
